Example Embodiment
[0024] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.
[0025] The basic idea of the present invention is to solve the problem of uncontrollable rotation speed caused by external force on the slewing mechanism during the slewing process of the crane. The present invention proposes a crane slewing control system. The slewing control system provided by the present invention is based on the free slip state. The parameters of the slewing load obtained by the lower detection adjust the slewing current range, thereby adjusting the slewing current, so that the slewing speed is automatically adjusted, and the stability of the slewing mechanism and the controllability of the operation are improved.
[0026] The preferred embodiment of the present ...
